Dengue viral diversity affected by prevalence of "competing" serotypes?: Relative abundance of dengue serotypes in Thailand fluctuates through time, as does genetic diversity within each serotype.
Influenza evolution and epidemic dynamics: Phylodynamics: mathematical model of influenza epidemics shows how viral evolutionary patterns can account for observed epidemic patterns of influenza, and ...
Avian influenza virus evolves rapidly in wild birds: Contrary to previous studies, research suggests that avian influenza A viruses in wild aquatic birds evolve at rates similar to those seen in influenza A in ...
Influenza evolution: the importance of chance processes: Extensive within-season genetic diversity in influenza A H3N2 viruses in New York State appears to arise from successive introduction of new variants from ...
Whole-genome analysis sheds light on influenza virus evolution: Evidence for multiple reassortment events in H3N2 influenza A viruses infecting humans.
Predicting the unpredictable: measles outbreaks in sub-Saharan Africa: Strong seasonal variations in transmission mean it is difficult to predict the size of measles epidemics in Niger from year to year. The large variability in ...
How yellow fever got to the Americas: Evolutionary analysis supports an "out of Africa" theory for the origin of South American yellow fever viral strains. The timing of the split between African ...
Hyperparasitic dengue viruses?: Field evidence that an evolutionary lineage of defective viruses can be transmitted by "parasitizing" functional proteins from other dengue viruses coinfecting ...
Recombination helps virus jump species?: Evidence that recombination may help viruses survive in novel environments, such as a new host species, from studies where domestic cats became infected with ...
Considerations for measles control in Africa: New models based on developing country data show that vaccination could limit measles epidemics within cities even once an epidemic has taken off.
Rapid evolution in a DNA virus: Human B19 erythrovirus demonstrates evolutionary rates more characteristic of RNA viruses.
Controlling foot-and-mouth disease by vaccination: A theoretical study indicates that certain reactive vaccination strategies may be able to halt foot-and-mouth spread more effectively than culling alone.
Dengue evolution: viral diversity in the Americas: Different patterns of spread and evolution in different types of dengue.
Commuting patterns and influenza epidemics: Mathematical models of annual influenza epidemics across the United States suggest that patterns of epidemic spread are affected by adults traveling to and ...
Tropical reservoir for human influenza?: An analysis of more than 1300 complete influenza genomes shows different evolutionary patterns for two important viral subtypes (A/H1N1 and A/H3N2). Changes in ...
Influenza A virus: history of reassortment: Genetic sequences collected between 1918 and 2005 indicate that reassortment happens frequently in the evolutionary history of the Influenza A virus, including ...
Why West Nile virus kills so many crows: West Nile virus infects many animals, including humans. The strain currently circulating in North America is particularly deadly to crows. A single positively ...
Rapid rise of antiviral resistance in influenza not caused by drug selection pressure: Over recent years, human influenza viruses resistant to antiviral drugs (adamantanes) have spread to high frequency worldwide. An analysis of influenza genomes ...
Human migrations not traceable by JC Virus after all: JC Virus has been used as a genetic marker to infer early human migration patterns. But new analyses show that it may be an unreliable indicator: this ...
Bacterial wilt and herbivory: Squash plants that resisted herbivory by beetles were also more resistant to a bacterial pathogen vectored by the beetles. This confounds some common ...
